  1. 1. On aircraft fuel systems : conceptual design and modeling

    Författare :Hampus Gavel; Petter Krus; Johan Ölvander (Andersson); Dieter Scholz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aircraft; morphological matrix; simulation; Saab; Gripen; Construction engineering; Konstruktionsteknik;

    Sammanfattning : The largest and most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. LÄS MER

  3. 2. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

    Författare :Venkata Raghu Chaitanya Munjulury; Petter Krus; Roland Stolt; Linköpings universitet; []
    Nyckelord :Knowledge-base; Aircraft; Conceptual Design; CAD; XML Database; Multidisciplinary; Optimization;

    Sammanfattning : With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design.

  4. 3. Constraint-based conceptual design using principle solution elements

    Författare :Sören Wilhelms; Christian Weber; Linköpings universitet; []
    Nyckelord :Conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The design of new products is an important engineering activity, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.During conceptual design, the principle solution for a product is conceived.

  5. 4. Reuse of principle solution elements in conceptual design : an information model for concepts in systematic design

    Författare :Sören Wilhelms; Linköpings universitet; []
    Nyckelord :conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Product development is an important activity in engineering design, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.The early phase of a systematic design process, namely conceptual design, during which the principle solution for a product is conceived, is of high importance for the later success of products.

  7. 5. Conceptual Design of Propulsion Systems for Boundary Layer Ingestion

    Författare :Sebastian Samuelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-electric aircraft; performance modeling; Aviation; boundary layer ingestion; aircraft engine; conceptual design; propulsion integration;

    Sammanfattning : To reduce the climate impact of aviation new aircraft and engine concepts as well as improved design methods are needed. In this thesis, two fronts are explored. The first concerns improved methods for the conceptual design of the engine. LÄS MER
